  • When and Why Would I Use a Mechanical Joint Lock Joint to Restrain Ductile Iron Pipe?

    When and Why Would I Use a Mechanical Joint Lock Joint to Restrain Ductile Iron Pipe?

    By Clinton CJ Fowler   06/30/2022  In Our Company Products Technical

    When it comes to restraining a water line, what comes to mind? Thrust blocks? Sure Stop 350® Gaskets? (locking gasket), TufGrip™ (wedge-action retainer gland), or maybe the standard default choice, TR Flex®? (Ductile iron restrained joint pipe). There is another option that might not regularly come to mind. It is known as Mechanical Joint Lock Joint or MJLJ for short. We will look at how the joint works, how it is installed, and locations where the MJLJ may be preferred.

    What Are The Benefits of DI Pipe vs. Concrete Cylinder Pipe?

    By Clinton CJ Fowler   09/02/2020  In Products

    Prestressed Concrete Cylinder Pipe (PCCP) has been used in water and wastewater applications for nearly 80 years. The thought process behind PCCP was sound, in that it would combine concrete's high compressive strength with steel's high tensile strength. However, like many products, PCCP has continued to fall short in the following years in many comparative categories to Ductile iron.

  • How to Repair Protecto 401™ Lining in The Field

    How to Repair Protecto 401™ Lining in The Field

    By Clinton CJ Fowler   04/18/2019  In Products Technical

    When talking about ductile iron pipe in sewer applications, many times Induron’s Protecto 401™   comes to mind. Protecto 401 lining has often been the specified lining for ductile iron pipe in sewer applications more than 50 years.

    Common uses for Protecto 401 are for a sewer force main that may not be fully running, where trapped air may exist, where chemical resistance is required, or for abrasion resistance. There may be occasions in the field when patching of the Protecto 401 lining may be necessary.
